The perfect thing to serve when you are entertaing both vegetarian and non-vegetarian guests. The grilled portobellos are wonderful served as a "steak" or sliced and served over pasta. They're even better served as a sandwich on french bread with sundried tomato pesto. Wow!

I have tried this recipe and thoroughly enjoyed it. For excellent flavour, it does require time to marinate the mushrooms - this may be considered by some as a downside but it really is worth the time. All it means is that you have to be somewhat organized - but that's not so bad.
Definitely a keeper and everyone who has tasted these mushrooms loves them.
